Don't buy Alva gas geyser

I bought an Alva gas geyser about a year ago. It worked well initially but with time it started giving problems with ingnition. So at this stage it does not click and ignite at all. Also Makro, where I bought the Alva gas geyser, never informed me that there are no spares available in South Africa. So if it breaks hoe does one fix it? Not impressed at all!
